Ok, I see your point.  My approach to this is a little different: I
think the "lottery" you describe should be moved outside the minibuffer
-- this was one of the main points for the in-buffer completion in
AUCTeX.  My way would be: Ok, I needed an optional argument but I missed
it, so I complete the current query and do it in the buffer later with
completion (if applicable) and don't start the whole query process.  But
that's only me.

See above; I don't argue against this, if Someone™ implements this :-)

That would be in a binding in `minibuffer-mode-map', right?

Best, Arash
